Photoresponsive Dioxazaborocanes‐Containing Oligomers

The synthetic methodology for the preparation of photoresponsive dioxazaborocanes‐containing oligomers is developed. It relies on the transformation of the (diisopropylamino)boryl group (−BH(NiPr2)) into a dioxazaborocane unit in the presence of β‐aminodiols and involves a bis‐borylated dithienyleth...

Description
Summary:The synthetic methodology for the preparation of photoresponsive dioxazaborocanes‐containing oligomers is developed. It relies on the transformation of the (diisopropylamino)boryl group (−BH(NiPr2)) into a dioxazaborocane unit in the presence of β‐aminodiols and involves a bis‐borylated dithienylethene photochromic unit. The photophysical properties of the obtained oligomers are evaluated as well as their processability for the preparation of spin‐coated films. The photomechanical behavior of the resulting films is assessed via displacement tracking profile. A new synthetic methodology for the preparation of photoresponsive oligomers containing dioxazaborocanes is developed from β‐aminodiols and a bis‐borylated dithienylethene photochromic unit. Their photophysical properties are evaluated, as well as their suitability for the preparation of spin‐coated films whose photomechanical behavior is assessed.
